Replace full-document snapshots with Arc first-touch deltas and batch cache invalidation. Reuse interaction and GPU category caches across unrelated edits.
Solid hatches carrying stale GradientColor1/2ACI EED (no ACAD_XREC_ROUNDTRIP
XRecord) no longer resurrect as a two-colour gradient — red / ACI-253 solids
now render solid instead of blue→yellow.

Heavy 2D POLYLINE vertices with absent width codes now inherit the
polyline default while explicit-zero segments stay zero, so tapered
polylines (e.g. sample_AC1009 handle 0x35B) render variable-width
instead of constant — matching the DWG/LWPOLYLINE form.

Companion to the acadrust DXF-fidelity sweep (bump to 379ce12):
- Legacy LEADER hookline: underline the annotation using the leader's own
stored text width (DXF code 41) when the MTEXT has no computed extents,
so the landing spans the text instead of a short stub.
- SHAPE: resolve the glyph by name when the shape number is 0 (DXF SHAPE
carries only the name), and search shape-file text styles when the entity
has no direct style reference.

Selecting a proxy object we render from its cached graphics (an AEC
Wall/Door/Window and the like) showed "Unknown" as its type. The entity
now carries its real DXF class name from the CLASSES section (acadrust
bump), so surface it: ui_name_or_class title-cases the class ("AEC_WALL"
→ "Aec Wall") for the properties Type row and the status-bar label, and
still says "Unknown" only when the class truly can't be named.

Multilines read from an R13–R2017 DWG (e.g. an AutoCAD 2013 save) lost
their per-element linetypes and drew every element solid instead of
dashed / with embedded text; R2018 saves were fine. The crate now decodes
the pre-R2018 bit_short linetype index.

A wipeout defined inside a block never masked the geometry once the block
was inserted — wipeout_models only scanned top-level entities, so the
wipeout was invisible unless you entered block-edit (where it is
top-level). It also drew a stray mask at its raw block-local coordinates
because the top-level scan lacked the block-defn reject the hatch path
uses.
Descend visible inserts and place each block-internal wipeout in world
space, applying the accumulated insert transform via apply /
apply_rotation. Add the belongs_to_visible_block filter so block-defn
wipeouts only appear through the descent, in world space.
Bumps acadrust for the matching transform_wipeout fix: its u/v basis was
double-scaled (apply_rotation then another scale-factor multiply), so a
scaled insert grew the mask; the descent sidesteps that path but the
explode/copy commands need the crate fix.

Pulls acadrust 022290a: recover_roundtrip_gradients is now gated to
pre-R2004. A native R2018 file whose hatch has its gradient turned off
(is_gradient=0, solid fill) but still carries stale GradientColor1/2ACI
round-trip EED no longer gets a spurious two-colour gradient painted over
it — the arrowhead / "Aluminium shading" hatches render solid as ODA and
libredwg decode them.

Brings the pre-2.0 SAT parse (single-line header, numeric edge/coedge
sense) so R14's ACIS 1.6 solids mesh into a full box, and the R13/R14
dictionary-key trim so an XCLIPped block resolves its spatial filter and
clips instead of drawing whole.

Brings two R14 (AC1014) decode fixes: down-saved gradient hatches now
recover through the case-insensitive EED / garbage-suffixed dictionary
key, and the R13/R14 DimStyle field block is finally read (DIMASZ /
DIMTAD / DIMGAP were stuck at defaults). The latter lets a leader hook
its annotation text — leader 1298's underline now spans the MTEXT
extents, matching the AC1032 render.

Solid hatches carrying GradientColor1ACI/GradientColor2ACI EED plus an
ACAD_XREC_ROUNDTRIP gradient XRecord now decode back into a real
gradient, so R2000-down-saved gradient fills render blue→yellow instead
of a flat solid. Color::rgb() already resolves the ACI stops, so the
existing gradient path picks them up with no render change.

Brings the pre-v700 (R2000) SAT edge decode fix: v400 edges omit the
start_param/end_param doubles, so reversed coedges were reading the
curve pointer as a vertex and every face with a reversed coedge loop
dropped out of the mesh. AC1015 solids/regions now tessellate to the
same triangle counts as the AC1018/AC1032 SAB decode (full box instead
of an open shell).

The horizontal attachment point was read from the entity-level field,
which only exists from R2010 on; older records (R2007 and earlier) left
it at the default and centre/right-attached leaders shifted. The
annotation context carries the same value in every version, so anchor
from there for both the render and the width-grip geometry.
acadrust bump also brings: the R2007 MULTILEADER tail gating (leaders no
longer render upside-down), the R2004-R2006 inline SAB payload read, the
v1-SAT wireframe point_present decode (3D solids/regions land in place
on R2000/R2004), and the XCLIPFRAME default of 2 so clip-frame borders
draw on files whose header omits the variable.

The annotation context is AutoCAD's baked display state; the renderer
now trusts it instead of re-deriving:
- text_attachment_point (L/C/R) is the stored horizontal anchor — the
leader-side guess shifted centre/right-attached texts by their width.
- ctx.text_direction/text_rotation apply as stored; forcing the
Horizontal angle type to 0 un-rotated angled leaders. The conn.y
baseline snap now applies only to unrotated text.
- The dogleg runs along the leader root's stored direction (angled
leaders drew it world-horizontal), and vertically-attached leaders
draw no dogleg at all.
- Underline attachments (BottomLine / BottomOfTopLineUnderline…) draw
the leader-coloured rule under the attached line(s), full text width.
- Vertical text flow (ctx.text_flow_direction) feeds the shared
vertical layout; frame/background boxes wrap the laid-out glyph
bounds padded by ctx.landing_gap, and run-less decoration strokes +
inline \C colours reach the output instead of being dropped.
- The wrap-width grip rides the shared flow_grip_axis() (rotation, flow
and attachment side), and its drag projects on the same axis.
acadrust bump: every MULTILEADER decodes (has_ds peek), MTEXT
top-to-bottom direction reads correctly.

The embedded solid display-cache wires are body-local (unplaced), and
R2013+ AcDs-backed solids used to misparse them into garbage points near
the origin — a clipped region rendered a stray fragment at (0,0,0). When
the ACIS payload parses, the mesh pipeline (fill + feature edges +
isolines, all body-placed) is the authoritative render, so the wires now
only serve as a last resort for unreadable ACIS data.
acadrust bump brings the decoded wireframe section and real reference
points: solids/regions report the file's stored bounding-box centre (or
a geometry-derived one) instead of (0,0,0), which feeds OCS grips,
Position properties and insertion snaps.

DWG stores no "hookline exists" flag (only the direction bit), so every
DWG-loaded leader kept hookline_enabled=false and drew no hook. Derive
it: a text-annotated leader hooks when its final segment leaves the
horizontal by more than 15°, shared by the render and snap/grip paths.
Hook length comes from the dim style like the arrowhead (DIMASZ ×
DIMSCALE), and with DIMTAD "text above" it extends under the annotation
to the far edge of the MTEXT's laid-out extents — newly exposed by
acadrust (lock bumped); the old text-height heuristic stays as the
no-style fallback.

Bump acadrust to a87435f: DXF encodes an off layer as a negative
code-62 colour index; the reader took 70 bit 2 ("frozen by default in
new viewports") as off instead. The AEC sample's GRIDLINES layer —
carrying that bit while fully visible in the DWG — imported hidden, so
every building axis line on it disappeared; genuinely off layers
imported visible. Second and final cause of #314, after the LTYPE
74/75 swap.
Closes#314

Bump acadrust to 6455610: the DXF LTYPE reader treated element code 74
as the shape number instead of the element-type flags and materialized
complex data on every plain dash — dashed linetypes like the AEC
sample's GRIDLINE turned "complex" with a null Shape{0} on each
element and rendered nothing. The DXF writer's swapped 74/75 emission
is fixed with it.
Closes#314

Bump acadrust to c5a579f: the DXF MULTILEADER reader now parses the
nested CONTEXT_DATA / LEADER / LEADER_LINE sections (leader lines and
text content used to come back empty, so DXF multileaders never
rendered), and the entity-level code map matches AutoCAD's real output
on both read and write (170 path type vs 172 content type).

Bump acadrust to 1e79519: the DXF reader now skips the R2018+
"101 / Embedded Object" section of MTEXT (and multiline ATTRIB/ATTDEF)
instead of letting its group codes overwrite the entity's already-parsed
insertion point, rotation, attachment and line spacing.
Closes#345

Follow-up to the LINE/POINT WCS fix - the same bug class elsewhere:
- 2D SOLID rendered its OCS corners raw in both the wire path and the
shared fill builder (solid_hatch_model); SHAPE placed its marker at
the raw OCS insertion. Both now map through the arbitrary axis.
- Grips: central wrap in view/dispatch.rs shows planar entities' grips
at their world position (OCS→WCS) and converts drags back (WCS→OCS
via the new wcs_point_to_ocs) - per-entity grip code stays in raw
field space, INSERT keeps handling its own OCS.
- Pulls acadrust 81ebfee: OCS-aware bounding boxes, translate,
transform and mirror for the ten planar entity types, so MOVE /
ROTATE / MIRROR and culling work on mirrored entities too.

wgpu/naga report pipeline and shader failures through the log facade,
then leave the canvas empty - with no logger installed on wasm the
message was lost, so a broken GPU path looked like "draws nothing" with
a clean console. Install a web logger that mirrors Error-level records
to the browser console and into a fixed DOM overlay with selectable
text, a Copy button and repeat-collapsing; panics land in the same
banner via a chained hook. Windows Chrome/Edge reporters can now paste
the exact ANGLE/D3D11 error instead of a screenshot of a blank canvas.

Bumps acadrust to 1b0a362: block headers no longer list handles of
